[0026] The beneficial effects of this application are as follows:

[0027] 1. By subjecting the wastewater to multi-stage treatment, including pretreatment, concentration, centrifugal separation and other steps, the present invention can effectively remove various pollutants in the wastewater. First, through the alternating use of the main dosing tank and the secondary dosing tank, continuous treatment of the wastewater is achieved, avoiding the waiting time in the treatment with a traditional single dosing tank and greatly improving the treatment efficiency. Secondly, the concentration tank performs secondary dosing and concentration on the preliminarily treated wastewater, further enhancing the treatment effect. Finally, the centrifugal dewatering machine performs centrifugal separation on the concentrated wastewater, efficiently separating the solid impurities from the clear water and ensuring the quality of the final effluent. This multi-stage treatment method not only improves the treatment efficiency, but also ensures the stability and reliability of the treatment effect.

[0028] 2. Through the design of the transmission rotating cylinder and the stirring blades, the mixing component of the present invention can efficiently and uniformly mix the wastewater and the medicament in the dosing and mixing ratio cylinder. The reduction motor drives the transmission rotating cylinder to rotate through the meshing of the main crown gear and the auxiliary crown gear, and then drives the stirring blades to stir the wastewater. This design not only improves the mixing speed, but also ensures the uniformity of mixing, avoiding the situation of too high or too low local medicament concentration, thereby improving the overall effect of wastewater treatment.

[0029] 3. Through the design of the drive shaft rod one and the mixing blades, the synergistic mixing and blending component of the present invention can not only stir and mix the wastewater and the medicament in the dosing and mixing ratio cylinder, but also cooperate with the adjustable scaling component to clean the inner wall of the dosing and mixing cylinder. The second drive sprocket drives a plurality of first drive sprockets to rotate through the chain condition, and then drives the drive shaft rod one to rotate, so that the mixing blades can not only perform efficient stirring, but also scrape off the impurities on the inner wall during rotation, reducing the workload of subsequent cleaning and improving the maintenance efficiency of the equipment.

[0030] 4. Through the design of the anti-settling and surging component, including the drive pull disc, the pull rod member, the pressure rod and the rubber plug, the present invention can effectively prevent the deposition of impurities and medicaments at the bottom of the inner cavity of the dosing and mixing ratio cylinder. The reduction motor drives the drive shaft rod two to rotate through the chain transmission member, and then lifts the pressure rod through the pull rod member, so that the rubber plug moves up and down in the transmission rotating cylinder, generating gas jets and driving the water body to surge. This design not only avoids the deposition phenomenon, but also increases the fluidity of the water body, improves the mixing efficiency of the medicament and the wastewater, and ensures the stability and reliability of the treatment effect.

[0031] 5. The adjustable zoom assembly of the present invention can flexibly adjust the position of the mixing blades through the design of the hydraulic rod, the toggle disc and the transmission shaft. When the stirring needs to be strengthened, the hydraulic rod can be used to push the toggle disc, so that the transmission shaft drives the mixing blades to retract inward, thereby enhancing the stirring effect. When the inner wall needs to be cleaned, the mixing blades can be expanded outward to scrape off impurities on the inner wall. This design not only improves the stirring efficiency, but also simplifies the maintenance of the equipment and reduces the labor intensity of the operator.

[0032] 6. The lifting assembly of the present invention is used in conjunction with the anti-sinking and surging assembly. Through the design of the push-connection support, the telescopic support cylinder and the transmission shaft rod 1, it can drive the efficiency-enhancing mixing assembly to move back and forth up and down. When the pressure rod moves up and down, through the cooperation of the push-connection support and the telescopic support cylinder, the transmission shaft rod 1 follows the up and down movement, thereby increasing the treatment range of the mixing blades for wastewater. This design not only improves the treatment efficiency, but also enhances the treatment effect, ensuring that impurities in the wastewater are effectively removed.

[0033] Ultimately, this solution significantly improved the efficiency and quality of wastewater treatment by implementing multi-stage treatment for thermal power plant wastewater. The equipment utilizes advanced pretreatment, concentration, and centrifugal separation technologies, combined with efficient mixing components, enhanced mixing components, anti-sinking and turbulence components, adjustable scaling components, and lifting components. This ensures the effective removal of harmful substances from the wastewater while reducing equipment maintenance costs and improving the safety and environmental friendliness of the treatment process. Furthermore, the equipment features a modular design, allowing for flexible configuration adjustments based on actual needs, adapting to wastewater treatment tasks of varying scales and types, demonstrating a high degree of flexibility and practicality.

[0034] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become obvious from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] The following describes a chemical dosing and separation water treatment device according to an embodiment of the present application with reference to the accompanying drawings.

[0072] As Figures 1-12 、 Figure 15 and Figure 16 shown, the chemical dosing and separation water treatment device according to an embodiment of the present application includes: a reservoir 100 for collecting wastewater, and a pre-sedimentation assembly is installed at the front end of the reservoir 100. Among them, the pre-sedimentation assembly includes a main chemical dosing tank 120 and a secondary chemical dosing tank 130 for preliminary precipitation and proportioning of wastewater impurities. The main chemical dosing tank 120 and the secondary chemical dosing tank 130 have the same function and are used alternately. For example, the wastewater in the reservoir 100 is pumped into the main chemical dosing tank 120 by a first suction pump group 200. After adding chemicals from a chemical storage tank 300 and stirring, a certain time is required for the stirring and proportioning. At this time, the first suction pump group 200 can be controlled to pump the wastewater in the reservoir 100 into the secondary chemical dosing tank 130. In this way, when the main chemical dosing tank 120 stirs and mixes the wastewater, the wastewater is injected into the secondary chemical dosing tank 130. Thus, in the case where both water delivery and stirring require time, by using the time difference, the two groups of the main chemical dosing tank 120 and the secondary chemical dosing tank 130 are used to preliminarily proportion and pre-sediment the wastewater and chemicals, improving the treatment efficiency of the wastewater and reducing the wastewater treatment time;

[0073] Specifically, the reservoir 100 further includes a water storage chamber 101 for storing mixed wastewater, and an aggregate bin 103 is installed on the right side of the water storage chamber 101. Among them, a filter mesh plate 102 is vertically and slidably inserted on the side opposite to the water storage chamber 101 and the aggregate bin 103. The filter mesh plate 102 is used to filter the wastewater, so that the filtered wastewater enters the cavity separated by the filter mesh plate 102, so that the input pipelines of the first suction pump group 200 can respectively pump the preliminarily filtered wastewater therein into the main chemical dosing tank 120 and the secondary chemical dosing tank 130;

[0074] Meanwhile, a frame 110 is installed on the surface of the water storage tank 100. The frame 110 can be used to fix the water storage tank 100, the main chemical addition tank 120, the secondary chemical addition tank 130, the concentration tank 140, and the centrifuge dehydrator 150 respectively. Among them, the bottom of the frame 110 is in contact with the ground, while the bottom of the water storage tank 100 is lower than the ground horizontal line. Therefore, during assembly, an assembly groove matching the water storage tank 100 needs to be opened on the ground, and the bottom of the water storage tank 100 is buried in the water body. This function can increase the overall stability of the water treatment equipment;

[0075] To avoid burying the bottom of the water storage tank 100 into the ground, feet can be installed at the front end of the frame 110, and the bottom of the feet is flush with the bottom of the water storage tank 100. In this way, the water storage tank 100 can be flat against the ground;

[0076] As a further optimization of this solution, a floating garbage elevator can be installed in the inner cavity of the water storage chamber 101. The output end of the floating garbage elevator is above the aggregate bin 103, and it can filter and lift the floating garbage in the water storage chamber 101 and send it into the aggregate bin 103 for storage;

[0077] Specifically, a concentration tank 140, a centrifuge dehydrator 150, and a water collection tank 160 are respectively installed on the left side of the secondary chemical addition tank 130 and at the end of the frame 110. Among them, the concentration tank 140 is used to re-dose and concentrate and deposit the wastewater preliminarily dosed and mixed in the main chemical addition tank 120 and the secondary chemical addition tank 130, avoiding the direct reaction of the wastewater in the main chemical addition tank 120 and the secondary chemical addition tank 130, resulting in impurities being easily retained in the main chemical addition tank 120 and the secondary chemical addition tank 130 and being difficult to clean. The centrifuge dehydrator 150 is used to centrifugally filter the wastewater after dosing treatment in the secondary chemical addition tank 130, the main chemical addition tank 120, and the concentration tank 140, so that it can separate the solid impurities generated by the dosing treatment from the clear water. The separated clear water is pumped into the water collection tank 160 under the action of the suction pump group four 230. The water collection tank 160 stores and collects the clear water for subsequent secondary use after passing the monitoring;

[0078] Specifically, a water quality detection group 170 is installed above the water collection tank 160. The water quality detection group 170 is used to detect the treated clear water in the water collection tank 160 to check whether it meets the treatment standard. The output end of the suction pump group five 240 is connected to two pipelines. One pipeline directly pumps out the clear water in the water collection tank 160, and the other pipeline is connected to the inner cavities of the main chemical addition tank 120 and the secondary chemical addition tank 130 for re-circulation to filter the unqualified wastewater again, so that it can pass the detection of the water quality detection group 170 and meet the water quality treatment standard;

[0079] Specifically, a water delivery component is provided above the frame 110. Among them, the water delivery component includes a first suction pump group 200, a second suction pump group 210, a third suction pump group 220, a fourth suction pump group 230, and a fifth suction pump group 240 respectively. The first suction pump group 200, the second suction pump group 210, the third suction pump group 220, the fourth suction pump group 230, and the fifth suction pump group 240 are all the same device and have the same function, which is to convey water bodies. The input end of the first suction pump group 200 extends into the reservoir 100 and communicates with the inner cavity on one side of the filter mesh plate 102 for pumping in the initially filtered wastewater, and the output end of the first suction pump group 200 communicates with the inner cavities of the main chemical addition tank 120 and the secondary chemical addition tank 130 respectively;

[0080] Specifically, the input end of the second suction pump group 210 communicates with the inner cavities of the main chemical addition tank 120 and the secondary chemical addition tank 130 respectively, and the output end of the second suction pump group 210 communicates with the inner cavity of the concentration tank 140. The input and output of the third suction pump group 220 communicate with the inner cavities of the concentration tank 140 and the centrifuge 150 respectively. The input and output ends of the fourth suction pump group 230 communicate with the inner cavities of the centrifuge 150 and the water collection tank 160 respectively. The input end of the fifth suction pump group 240 communicates with the inner cavity of the water collection tank 160. Among them, two pipelines are connected to the output end of the fifth suction pump group 240. One pipeline directly pumps out the clear water in the water collection tank 160, and the other pipeline communicates with the inner cavities of the main chemical addition tank 120 and the secondary chemical addition tank 130 for re - circulation to perform re - filtration treatment on unqualified wastewater;

[0081] Specifically, electromagnetic control valves are installed at the input and output ends of the first suction pump group 200, the second suction pump group 210, the third suction pump group 220, the fourth suction pump group 230, and the fifth suction pump group 240 to control the opening and closing of their cavities;

[0082] A plurality of chemical reagent storage tanks 300 are installed at the rear sides of the ends of the main chemical addition tank 120 and the secondary chemical addition tank 130. There are multiple chemical reagent storage tanks 300 and they store different treatment chemicals. A plurality of concentrated chemical reagent bins 310 are erected at the ends of the concentration tank 140. Multiple concentrated treatment chemicals are respectively arranged in the plurality of concentrated chemical reagent bins 310. Among them, the chemical reagent storage tanks 300 and the concentrated chemical reagent bins 310 respectively perform precise feeding into the main chemical addition tank 120, the secondary chemical addition tank 130, and the concentration tank 140 through metering pumps: precisely controlling the dosage of the chemicals to ensure the uniform distribution and effective action of the chemicals; and the input ends of the chemical reagent storage tanks 300 and the concentrated chemical reagent bins 310 are connected to the external chemical delivery pipeline through pipelines;

[0083] Specifically, the chemical storage tank 300 stores a variety of treatment chemicals, and the concentrated chemical bin 310 can also store a variety of concentrated precipitation chemicals.

[0107] Specifically, the dosing and mixing cylinder 400 is vertically arranged in the inner cavities of the main dosing tank 120 and the auxiliary dosing tank 130, and the bottom surface of the opposite dosing and mixing cylinder 400 is communicated with the inner cavities of the main dosing tank 120 and the auxiliary dosing tank 130 through openings; a filtering ring plate 410 is sleeved on the end of the outer surface of the dosing and mixing cylinder 400. Among them, the output end of the suction pump group 200 is located at the end of the filtering ring plate 410 for re-filtering the pumped wastewater to reduce impurities. The front end of the front surface of the main dosing tank 120 and the auxiliary dosing tank 130 is penetrated and installed with a debris cleaning box for cleaning and discharging the sundries collected by the filtering ring plate 410. The bottom of the dosing and mixing cylinder 400 penetrates to the bottom of the inner cavity of the frame 110, and the connection between the dosing and mixing cylinder 400 and the frame 110 is rotationally connected through a bearing. One side of the bottom of the concentration tank 140 is installed with a driving motor 420. Among them, a gear transmission group 430 is installed at the bottom of the driving motor 420. The gear transmission group 430 is two meshing transmission gears. As Figure 7 shown, one transmission gear is connected to the output end of the gear transmission group 430, and the other transmission gear is sleeved on the bottom surface of the dosing and mixing cylinder 400. Therefore, when the driving motor 420 rotates, it can drive the dosing and mixing cylinder 400 to rotate through the gear transmission group 430; this facilitates subsequent cleaning of the inner wall of the dosing and mixing cylinder 400 by the mixing blades 620;

[0108] The drug mixing cylinder 400 is divided into two sections, with the bottom horizontal surface of the main drug adding tank 120 as the center boundary. The upper section of the drug mixing cylinder 400 is used to mix the wastewater to be added, while the lower section of the drug mixing cylinder 400 is used to install the transmission gear on the gear transmission group 430 so that the drive motor 420 can drive the entire drug mixing cylinder 400. The upper and lower sections of the drug mixing cylinder 400 are preferably in a non-connected state.

[0109] Specifically, the mixing assembly 500 is vertically arranged in the middle section of the dispensing mixing cylinder 400, wherein the mixing assembly 500 includes a transmission drum 510 and a reduction motor 520 for driving the transmission drum 510. A plurality of stabilizing collars 511 are installed from top to bottom in the inner cavity of the mixing assembly 500, and air holes are formed through the inner surface of the transmission drum 510. The inner surface of the stabilizing collar 511 is in sliding contact with the outer surface of the pressure rod 750, and the outer surface of the stabilizing collar 511 is fixedly connected to the inner wall of the transmission drum 510. Therefore, the stabilizing collar 511 can increase the stability between the transmission drum 510 and the pressure rod 750.

[0110] In order to support the reduction motor 520, a fixed support 530 is provided at the bottom of the reduction motor 520. Therefore, the reduction motor 520 is fastened to the surface of the fixed support 530 by bolts. At the same time, the opposite fixed supports 530 are fastened to the ends of the main dosing box 120 and the auxiliary dosing box 130 by bolts respectively. The output end of the reduction motor 520 is connected to the main crown gear 540. At the same time, the shaft end of the surface of the transmission drum 510 is sleeved with an auxiliary crown gear 541, wherein the auxiliary crown gear 541 and the main crown gear 540 are meshed with each other. A plurality of stirring blades 550 are sleeved on the surface of the transmission drum 510 and located in the inner cavity of the dispensing mixing drum 400.

[0111] Specifically, the bottom of the transmission drum 510 passes through the bottom of the dial disc 820 and the fixed base 810 and is movably connected to the connection point via a bearing. The end of the surface of the transmission drum 510 and the end of the fixed base 810 are sleeved and connected to a ball slide. The ball slide is slidably connected to the end of the fixed base 810. Therefore, when the transmission drum 510 rotates, the ball slide slides on the end of the fixed base 810, thereby helping to support the transmission drum 510.

[0112] Finally, when the reduction motor 520 rotates, it can drive the transmission drum 510 to rotate under the cooperation of the main crown gear 540 and the auxiliary crown gear 541, and then drive the stirring blades 550 mounted on the surface of the transmission drum 510 to rotate. The stirring blades 550 are used to mix the wastewater in the mixing drum 400 with the added treatment liquid, quickly mixing the two and increasing the reaction treatment efficiency of the wastewater.

[0113] Meanwhile, on the outer side of the driving rotating cylinder 510 and inside the medicine dispensing and mixing ratio cylinder 400, an efficiency-enhancing mixing assembly 600 for increasing the reaction rate of wastewater is installed. The efficiency-enhancing mixing assembly 600 includes a first transmission shaft rod 610 for driving and a plurality of mixing blades 620 sleeved on the surface of the first transmission shaft rod 610. The mixing blades 620 can stir and clean the inner wall of the medicine dispensing and mixing ratio cylinder 400, and the mixing blades 620 are designed for multiple purposes;

[0114] Among them, there are multiple first transmission shaft rods 610. The number of the first transmission shaft rods 610 is not limited to the four shown in the figure. And the filtering ring plate 410 is tightly arranged in a ring shape inside the medicine dispensing and mixing ratio cylinder 400. The mixing blades 620 in a rotating state can stir and mix the wastewater and the added medicine in the main medicine adding tank 120 and the auxiliary medicine adding tank 130, increasing the stirring efficiency of the stirring blades 550;

[0115] As a further optimization of this solution, the inner cavity space on the opposite side of the medicine dispensing and mixing ratio cylinder 400 and the main medicine adding tank 120 can be set to be solid. The space inside the medicine dispensing and mixing ratio cylinder 400 is reserved as the medicine adding and mixing space, and the pre-filtration of the incoming wastewater by the filtering ring plate 410 is cancelled to avoid impurities adhering to the inner walls of the main medicine adding tank 120 and the auxiliary medicine adding tank 130;

[0116] Furthermore, a rotating sleeve 630 is sleeved on the end of the outer surface of the first transmission shaft rod 610. Among them, a first transmission sprocket 640 is sleeved on the outer surface of the rotating sleeve 630, and a second transmission sprocket 660 is sleeved on the end of the surface of the driving rotating cylinder 510. Among them, a chain 670 is meshed and connected to the surfaces of the plurality of first transmission sprockets 640 and the second transmission sprocket 660. Thus, when the second transmission sprocket 660 rotates under the influence of the driving rotating cylinder 510, it can drive the plurality of first transmission sprockets 640 to rotate, and then drive the rotating sleeve 630 to rotate. Finally, the rotating sleeve 630 is used to drive the first transmission shaft rod 610 to rotate, so that the first transmission shaft rod 610 drives the mixing blades 620 to mix the wastewater and the medicine in the medicine dispensing and mixing ratio cylinder 400;

[0117] The cam 630 is provided with a plurality of sliding grooves 611 on the end of the surface of the transmission shaft 610, and a sliding plug 631 is connected to the inner surface of the rotating sleeve 630. The sliding plug 631 and the sliding groove 611 are used in conjunction with each other, wherein the sliding plug 631 is inserted into the inner cavity of the sliding groove 611 and is in sliding contact with the connection therewith. Therefore, when the rotating sleeve 630 rotates, the sliding plug 631 can be used to press against the inner cavity of the sliding groove 611 to drive the transmission shaft 610 to rotate. The connection between the sliding groove 611 and the sliding plug 631 is lubricated. The top of the surface of the transmission shaft 610 is provided with an auxiliary support sliding seat 612, and the bottom of the auxiliary support sliding seat 612 is in rotational contact with the telescopic end of the telescopic support tube 910. The telescopic support tube 910 and the auxiliary support sliding seat 612 cooperate to help increase the stability of the transmission shaft 610 during rotation.

[0118] Specifically, an annular groove is formed at the end of the surface of the transmission shaft 610 and located above the auxiliary support sliding seat 612, and a slip ring is provided through one end of the upper clamping plate 920. The slip ring is slidably disposed in the inner cavity of the annular groove on the transmission shaft 610. In this way, the transmission shaft 610 and the upper clamping plate 920 can be slidably mounted together to prevent the upper clamping plate 920 from rotating with the transmission shaft 610.

[0119] The bottom of the rotating sleeve 630 is provided with a support slide 650, which is slidably disposed in the linear slide 811. Therefore, when the relative position of the transmission shaft 610 is changed, the support slide 650 slides linearly within the linear slide 811.

[0120] Finally, when the transmission drum 510 rotates, the second transmission sprocket 660, the chain link 670, and the first transmission sprocket 640 cooperate to drive the rotating sleeve 630 to rotate. Under the action of the sliding groove 611 and the sliding insert 631, the first transmission shaft 610 is moved to rotate. Under the cooperation of the sliding groove 611 and the sliding insert 631, the first transmission shaft 610 can also rotate when the first transmission shaft 610 is subsequently pulled up and down.

[0121] Specifically, an anti-sinking and surging component 700 for preventing the deposition of impurities and medicines is further provided in the middle of the inner cavity of the mixing cylinder 400. The anti-sinking and surging component 700 includes a transmission pull plate 710 and a pull rod 730. In order to drive the transmission pull plate 710, a transmission shaft rod 2 720 is embedded and installed in the center of the transmission pull plate 710. In order to increase the stability of the transmission shaft rod 2 720, a support shaft rod 721 is provided on the surface of the transmission shaft rod 2 720 through a bearing movable sleeve, wherein the other end of the support shaft rod 721 is fixed to the fixed support. The surface of the gear reducer 520 is connected to the surface of the gear reducer 530, thereby auxiliaryly supporting the second transmission shaft 720 and the transmission pull plate 710 under the cooperation of the fixed support 530 and the supporting shaft 721. The output end of the reduction motor 520 and the surface of the second transmission shaft 720 are both sleeved with a chain transmission member 740, and the two chain transmission members 740 are meshed with each other. Therefore, when the reduction motor 520 is working and its output end rotates, it can not only drive the main crown gear 540 to rotate, but also drive the second transmission shaft 720 through the chain transmission member 740 to rotate the transmission pull plate 710;

[0122] Specifically, the two chain transmission members 740 are arranged in a large and a small configuration, wherein the large chain transmission member 740 is sleeved on the output end of the reduction motor 520, and the small chain transmission member 740 is sleeved on the surface of the second transmission shaft 720. By adjusting the gear ratio of the two chain transmission members 740, the rotation speed of the second transmission shaft 720 can be increased, and then the pressure rod 750 can be quickly pulled back and forth. The pressure rod 750 and the rubber stopper 760 are used to extract air, and the inside of the mixing cylinder 400 is sprayed, which drives the liquid at the bottom of the inner cavity of the mixing cylinder 400 to surge, thereby preventing impurities and material from being deposited at the bottom of the inner cavity of the mixing cylinder 400.

[0123] Specifically, a pressure rod 750 is provided at the bottom of the pull rod 730, wherein the two ends of the pull rod 730 are respectively connected to the axial ends of the transmission pull plate 710 and the pressure rod 750 through a universal shaft. Therefore, when the transmission pull plate 710 rotates, the pull rod 730 can be driven to pull the pressure rod 750, causing it to move up and down, thereby driving the rubber stopper 760 to move back and forth.

[0124] Specifically, the bottom of the pressure rod 750 penetrates into the inner cavity of the transmission rotating cylinder 510 and is connected with a rubber plug 760. The inner cavity diameter of the transmission rotating cylinder 510 at the end of the rubber plug 760 is widened. Therefore, when the pull rod member 730 on the transmission pull disc 710 drives the pressure rod 750 to move upward, the rubber plug 760 can be driven to move upward into the widened inner cavity of the transmission rotating cylinder 510, so as to facilitate the entry of gas into the transmission rotating cylinder 510. When the pressure rod 750 drives the rubber plug 760 to move downward, the gas entering the transmission rotating cylinder 510 can be compressed downward and discharged into the water body in the medicine dispensing and mixing cylinder 400 through the jet inclined pipe 770 and the nozzle 780, and the gas is used to drive the water body to surge, increasing the fluidity of the water body and the medicine during treatment and preventing impurities or medicine from sinking to the bottom;

[0125] Specifically, the anti-settling and surging assembly 700 further includes a jet inclined pipe 770. Among them, a plurality of nozzles 780 are communicated with the surface of the jet inclined pipe 770, and the input end of the jet inclined pipe 770 is communicated with the bottom of the inner cavity of the transmission rotating cylinder 510. Among them, the input end of the nozzle 780 is made one-way, for example, a one-way valve is installed on the surface of the nozzle 780, so as to avoid the liquid flowing back into the nozzle 780;

[0126] Finally, when the transmission rotating cylinder 510 and the stirring blades 550 stir the wastewater in the medicine dispensing and mixing cylinder 400, the moving pressure rod 750 can be used to drive the rubber plug 760 to perform a suction and pressurization action in the transmission rotating cylinder 510, suck the gas and blow it into the water in the medicine dispensing and mixing cylinder 400, and surge the particulate matter at the bottom of the inner cavity of the medicine dispensing and mixing cylinder 400 to prevent the particulate matter from depositing. At the same time, the transmission rotating cylinder 510 can rotate, so that the jet inclined pipe 770 rotates to cooperate with the stirring blades 550 to surge the particulate matter in the inner cavity of the medicine dispensing and mixing cylinder 400 in all directions, increasing the fluidity of the water body and improving the efficiency of wastewater medicine adding and mixing treatment.

[0127] Such as Figures 12-15 and Figure 17It is shown that in the process of implementing multi-stage circulation treatment of wastewater generated by thermal power plants, the dosing and mixing pretreatment can be completed quickly, prompting the wastewater to undergo rapid chemical reactions. The pretreated wastewater will be pumped into the concentration tank 140 for secondary concentration, and will be quickly centrifuged by the centrifugal dehydrator 150. However, after the dosing and mixing pretreatment stage, a large number of impurity particles produced by chemical reactions will adhere to the inner wall of the dosing mixing cylinder 400. These impurity particles make the subsequent cleaning work complicated, time-consuming and labor-intensive. At the same time, the transmission shaft 1610 in the synergistic mixing component 600 can only achieve rotary stirring and mixing of the water body, and it is difficult to further optimize on this basis to improve the mixing efficiency of the transmission shaft 1610 and the mixing blades 620 for the dosing wastewater. Therefore, the dosing and separation water treatment equipment also includes an adjustable scaling component 800 and a lifting component 900, wherein the adjustable scaling component 800 is used to adjust the positions of multiple transmission shafts 1610 so that multiple transmission shafts 1610 can drive adjacent mixing The mixing blades 620 can be retracted inward or expanded outward, so that the retracted mixing blades 620 can re-mix the dosing wastewater. When the mixing blades 620 are expanded outward, they are close to the inner wall of the dosing mixing cylinder 400 to clean the impurities attached to the inner wall of the dosing mixing cylinder 400, thereby reducing the labor intensity of subsequent cleaning. The lifting assembly 900 can drive the synergistic mixing assembly 600 to reciprocate up and down, thereby increasing the treatment efficiency of the synergistic mixing assembly 600 for the dosing wastewater.

[0128] Specifically, the adjustable zoom assembly 800 includes a fixed chassis 810 and a dial disc 820 disposed above the fixed chassis 810. There are multiple fixed chassis 810, and adjacent fixed chassis 810 are fastened to adjacent ends of the main dosing box 120 by bolts. To support the dial disc 820, a sliding support seat 830 is provided on the outer surface of the dial disc 820, and the bottom of the sliding support seat 830 is fastened to the end of the fixed chassis 810 by bolts.

[0129] Specifically, a plurality of linear grooves 811 are formed on the surface of the fixed chassis 810, and the support slide 650 is slidably disposed in the inner cavity of the linear grooves 811. A push-connection groove 821 is formed on one side of the end of the toggle disc 820. The push-connection groove 821 cooperates with the push-connection support shaft 850, and the surface of the push-connection support shaft 850 is slidably disposed in the inner cavity of the push-connection groove 821. At the same time, a plurality of arcuate push grooves 822 are formed on the outer ring of the surface of the toggle disc 820, and the arcuate push grooves 822 are in sliding contact with the shaft end of the surface of the rotating sleeve 630.

[0130] Specifically, a hydraulic rod 840 is mounted on one side of the end of the fixed chassis 810, wherein the output end of the hydraulic rod 840 is movably connected to the pushing support shaft 850 through a rotating shaft, and the surface of the pushing support shaft 850 is sleeved with a transmission sprocket 3 860, wherein the transmission sprocket 3 860 is movably sleeved on the surface of the pushing support shaft 850 through a bearing, so as to prevent the transmission sprocket 3 860 from driving the pushing support shaft 850 to rotate with it when it rotates, wherein a stabilizing groove cavity is linearly opened on the surface of the fixed chassis 810 and located at the bottom of the pushing support shaft 850, and the shaft end of the pushing support shaft 850 is slidably arranged in the inner cavity of the stabilizing groove cavity, wherein the inner cavity of the stabilizing groove cavity is installed with a straight rod, the surface of the rod passes through the inner surface of the pushing support shaft 850 and is in sliding contact with it, so as to increase the stability of the pushing support shaft 850 during linear movement;

[0131] Thus, when adjusting the relative positions of the plurality of transmission shafts 1 610 in the synergistic mixing assembly 600, when adjusting outward, the telescopic end of the hydraulic rod 840 is controlled to extend back, driving the pushing support shaft 850 to shift the pushing slide 821 to rotate. When the pushing slide 821 rotates, under the limit of the linear slide 811, the arc-shaped shifting groove 822 shifts the rotating sleeve 630 to drive the transmission shaft 1 610 to extend outward. While the rotating sleeve 630 drives the transmission sprocket 1 640 to extend outward, the pushing support shaft 850 drives the transmission sprocket 3 860 to retract inward, so that the chain link 670 can be tightly engaged with the surfaces of the transmission sprocket 1 640 and the transmission sprocket 3 860.

[0132] The hydraulic rod 840 drives the pushing support shaft 850 to extend and retract, which has two advantages. First, when the pushing support shaft 850 extends inward, the pushing slide 821 cooperates with the pushing slide 821 to drive the toggle disc 820 to rotate, without requiring any external power source for the toggle disc 820. Second, when the rotating sleeve 630 drives the transmission sprocket 1 640 to extend and retract, the hydraulic rod 840 drives the pushing support shaft 850 to adjust the position of the transmission sprocket 3 860, so that the chain condition 670 can be dynamically adjusted, thereby avoiding the problem that the chain condition 670 limits the position of multiple transmission sprockets 640 when they are extended and retracted, causing the multiple transmission sprockets 640 to be unable to retract.

[0133] Specifically, the lifting assembly 900 includes a push-connection support 930, which is sleeved on the axial end of the pressure rod 750. A plurality of limiting slide bars 931 are provided on the surface of the push-connection support 930, and the bottom of the limiting slide bar 931 passes through the push-connection support 930 and is connected to the top of the fixed support 530. The connection between the limiting slide bar 931 and the push-connection support 930 is in sliding contact.

[0134] Specifically, telescopic support cylinders 910 are provided at the four corners of the bottom of the push-connecting support 930. The telescopic support cylinders 910 can expand outwards telescopically. On the contrary, when subjected to a reverse force, the output ends of the telescopic support cylinders 910 can also retract inwards. The bottom of the telescopic support cylinders 910 is fixedly connected to the end of the fixed support 530 by bolts. The output ends of the telescopic support cylinders 910 are fixedly connected with lower clamping plates 911, and the ends of the lower clamping plates 911 are in sliding contact with the surface of the push-connecting support 930. Upper clamping plates 920 are provided around the periphery of the end of the push-connecting support 930. Among them, the upper clamping plates 920 and the lower clamping plates 911 are used in combination. Among them, the telescopic support cylinders 910 are movably installed on the surface of the first transmission shaft rod 610 through bearings, and the upper clamping plates 920 and the lower clamping plates 911 are connected by support rods;

[0135] Specifically, the annular groove provided on the surface of the first transmission shaft rod 610 is used in combination with the sliding ring penetrating through one end of the upper clamping plate 920. The two can not only be in sliding contact, but also, under the action of the sliding ring, when the push-connecting support 930 is lifted by the acting force of the pressure rod 750, the first transmission shaft rod 610 can be lifted under the combined clamping action of the upper clamping plate 920 and the lower clamping plate 911, so that the first transmission shaft rod 610 can not only rotate, but also rotate up and down when rotating. In this way, the efficiency of the mixing blade 620 for treating the added medicine and wastewater in the medicine mixing ratio cylinder 400 is increased;

[0136] In this way, by using the lower clamping plate 911 and the upper clamping plate 920 to be able to clamp on the surface of the push-connecting support 930, the movement of the push-connecting support 930 can drive the first transmission shaft rod 610 to move with it, and the telescopic support cylinders 910 can assist in supporting the first transmission shaft rod 610. At the same time, when multiple first transmission shaft rods 610 extend outwards, the output ends of the telescopic support cylinders 910 are pulled outwards by the tension force. In this way, the moving first transmission shaft rod 610 can be flexibly assisted in supporting.

[0137] Specifically, the working principle of this added medicine and separated water treatment equipment:

[0138] Pretreatment stage: The wastewater is first pumped from the reservoir 100 into the main medicine adding tank 120 or the auxiliary medicine adding tank 130 by the first suction pump group 200. Under the medicine feeding of the medicine storage tank 300 and the stirring of the stirring blades 550, preliminary medicine adding and mixing are carried out. The main medicine adding tank 120 and the auxiliary medicine adding tank 130 are used alternately to ensure the continuity and high efficiency of wastewater treatment.

[0139] Concentration stage: The preliminarily treated wastewater is pumped into the concentration tank 140 by the second suction pump group 210. Under the medicine feeding and stirring of the concentrated medicine bin 310, secondary concentration treatment is carried out. The design of the concentration tank 140 avoids the residue of the medicine in the main medicine adding tank 120 and the auxiliary medicine adding tank 130 and improves the treatment effect.

[0140] Centrifugal separation stage: The concentrated wastewater is pumped into the centrifuge 150 by the suction pump group three 220 for centrifugal separation. The centrifuge 150 separates the solid impurities from the clear water in the wastewater by high-speed rotation. The separated clear water is pumped into the water collection tank 160 by the suction pump group four 230 for storage.

[0141] Water quality detection and reprocessing stage: The clear water in the water collection tank 160 is detected by the water quality detection group 170. If the water quality does not meet the standard, the unqualified wastewater is pumped back into the main chemical addition tank 120 or the secondary chemical addition tank 130 by the suction pump group five 240 for reprocessing until the water quality meets the standard.

[0142] Auxiliary functions: During the whole treatment process, the mixing component 500 and the synergistic mixing and compounding component 600 ensure the full mixing of the chemicals and the wastewater through efficient stirring and inner wall cleaning; the anti-settling and surging component 700 prevents impurity deposition through gas injection; the adjustable scaling component 800 and the lifting component 900 further improve the treatment efficiency and effect by flexibly adjusting the position of the mixing blade 620 and moving it up and down.
